I used the iPhone for 6 months (work phone) and purchased a Samsung model as a replacement (in the 2 weeks). I'm not sure how you could confuse the 2 phones.

I used the iPhone for 6 months (work phone) and purchased a Samsung model as a replacement (in the 2 weeks). I'm not sure how you could confuse the 2 phones. The functionality of the two are different enough that confusing the two is difficult. If the similarity is based on icons and using icons to open programs, wasn't this done at PARC? Or the original Mac? I'd think those are both prior art, or possibly even the Palm PDAs. At this point I'm not sure which phone I like better, both tend to work which is my main requirement.
